Android üzerinden Mac OS X'e android istemcisinden mesaj göndermeye çalışıyorum. Mac OS X Snow Leopard'da bluecove 2.0.1 Java bluetooth kütüphanesi kullanıyorum. Serverandroid üzerindeki bluetooth soketine bağlanamıyor
Kodu:
public class EchoServer2 {
private static final String UUID_STRING = "00001101-0000-1000-8000-00805F9B34FB"; // 32 hex digits
private static final String SERVICE_NAME = "echoserver";
private LocalDevice mLocalDevice;
public EchoServer2() {
try {
mLocalDevice = LocalDevice.getLocalDevice();
} catch(IOException e) {
System.err.print("Error connection to bluetooth");
}
}
public void start() throws IOException {
StreamConnectionNotifier connectionNotifier =
(StreamConnectionNotifier) Connector.open(
"btspp://localhost:" + UUID_STRING +
";name=" + SERVICE_NAME + ";authenticate=false");
System.out.println("Bluetooth Address: " + mLocalDevice.getBluetoothAddress());
System.out.println("Waiting for a connection...");
StreamConnection streamConnection = connectionNotifier.acceptAndOpen();
System.out.println("Found a new device.");
RemoteDevice device = RemoteDevice.getRemoteDevice(streamConnection);
System.out.println("New Device connected: " + device.getFriendlyName(false).toString());
DataInputStream is = streamConnection.openDataInputStream();
byte[] bytes = new byte[1024];
int r;
while((r = is.read(bytes)) > 0) {
System.out.println(new String(bytes, 0, r));
}
}

ben UUID
olmasına rağmen sunucuya bağlanabiliyor değilim İstemci ve sunucu için aynı. Android bir istisna atar: Hizmet Bulma başarısız oldu. Ancak, sunucudaki uzak aygıtın (istemci) adını yazdıramıyorum. Dolayısıyla acceptAndOpen()
soket bağlantısını kabul edemiyor.
Lütfen neden clientSocket.connect()
; Android'de mi?
Bunu çözmeyi başardınız mı? Tam olarak aynı problemi yaşıyorum ve işe yaramış gibi görünmüyorum. – blastervla
